S3: substrate (34) is placed at workbench slot (20) center or is taken out weldment；Adjust shock plate (13) and substrate
The distance between (34)；
S4: being moved to the left by three coordinate mobile cylinder controllers (38) control cylinder (19), pushes right work by push rod (23)
Plug (28) is moved to the left, while left piston (31) compressed spring (32)；Since swingle (30) is contacted with right piston (28), so
Right piston (28) pushes swingle (30) to rotate clockwise around pin (15), drives left lower link (21) and upper right connecting rod (25) respectively
It is moved outside to workbench (34), both sides briquetting (14) rotation is pushed to compress；At the same time, swingle (30) rotation leads to inclined wedge machine
Structure pressure release, spring (32) push inclined wedge (17) to there is movement, and traveller (16) moves downward, and workbench slot (20) resets；
S5: it is adjusted between shock plate (13) and substrate (34) by computer (1) control constraints layer apparatus for adjusting position (10)
Distance；The position that three coordinate mobile platforms (35) are adjusted by three coordinate cylinder mobile controllers (38), so that pulse laser
(3) laser beam (4) exported focuses on absorbed layer (12) by reflecting mirror (5) and condenser lens (6)；Pass through condenser lens position
It sets regulating device (8) and adjusts condenser lens (6) at a distance from absorbed layer (40), to adjust hot spot；
S6: the laser beam (4) that computer (1) accurately controls acts on absorbed layer (12), generates explosion plasma, and plasma drives
Dynamic shock plate (13) high-speed cruising, hits substrate (29), realizes welding；
S7: repeating S2, S3, S4, S5, S6, S7, it can be achieved that shock plate (13) and the batch of substrate (23) weld.
9. a kind of laser-impact according to claim 8 welds automated exchanged cutter method, which is characterized in that the shock plate
(13) and substrate (23) is of the same race or different metal materials.
10. a kind of laser-impact according to claim 8 welds automated exchanged cutter method, which is characterized in that the shock plate
(13) with a thickness of 20 μm -40 μm, substrate (34) with a thickness of 50 μm -100 μm；The restraint layer (12) is 2mm-4mm thick
Transparent Asia make every effort to overcome plate, the absorbed layer (40) is pitch-dark, thickness 0.05mm-0.2mm.
